Presidential candidates are individuals who run for the office of President of a country. They typically come from political parties and campaign for support from voters in order to win the election. Presidential candidates often present their policies, beliefs, and qualifications to the public through debates, speeches, and advertisements. They compete in primary elections within their party to become the official nominee, and then face off against candidates from other parties in the general election. The role of presidential candidates is to represent their party and its platform, engage with voters, and ultimately lead the country if elected.
